CSS: Changes for SDS framework

This patch does the required changes to enable CSS platforms
to build and use the SDS framework. Since SDS is always coupled with
SCMI protocol, the preexisting SCMI build flag is now renamed to
`CSS_USE_SCMI_SDS_DRIVER` which will enable both SCMI and SDS on
CSS platforms. Also some of the workarounds applied for SCMI are
now removed with SDS in place.

Export KEY_ALG as a user build option

The `KEY_ALG` variable is used to select the algorithm for key
generation by `cert_create` tool for signing the certificates. This
variable was previously undocumented and did not have a global default
value. This patch corrects this and also adds changes to derive the
value of `TF_MBEDTLS_KEY_ALG` based on `KEY_ALG` if it not set by the
platform. The corresponding assignment of these variables are also now
removed from the `arm_common.mk` makefile.

ARM plat changes to enable CryptoCell integration

This patch makes the necessary changes to enable ARM platform to
successfully integrate CryptoCell during Trusted Board Boot. The
changes are as follows:

* A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select
the CryptoCell crypto driver for Trusted Board boot.

* The TrustZone filter settings for Non Secure DRAM is modified
to allow CryptoCell to read this memory. This is required to
authenticate BL33 which is loaded into the Non Secure DDR.

* The CSS platforms are modified to use coherent stacks in BL1 and BL2
when CryptoCell crypto is selected. This is because CryptoCell makes
use of DMA to transfer data and the CryptoCell SBROM library allocates
buffers on the stack during signature/hash verification.

This options enables an implementation of SHA-256 that has a smaller
code footprint (~1.6 KB less) but is also ~30% slower. For ARM
platforms, code size is currently considered more important than
execution speed in the mbed TLS crypto module.

Added a small note about this option to the documentation of the
authentication framework.

Introduce ARM SiP service to switch execution state

In AArch64, privileged exception levels control the execution state
(a.k.a. register width) of the immediate lower Exception Level; i.e.
whether the lower exception level executes in AArch64 or AArch32 state.
For an exception level to have its execution state changed at run time,
it must request the change by raising a synchronous exception to the
higher exception level.

This patch implements and adds such a provision to the ARM SiP service,
by which an immediate lower exception level can request to switch its
execution state. The execution state is switched if the request is:

- raised from non-secure world;

- raised on the primary CPU, before any secondaries are brought online
with CPU_ON PSCI call;

- raised from an exception level immediately below EL3: EL2, if
implemented; otherwise NS EL1.

If successful, the SMC doesn't return to the caller, but to the entry
point supplied with the call. Otherwise, the caller will observe the SMC
returning with STATE_SW_E_DENIED code. If ARM Trusted Firmware is built
for AArch32, the feature is not supported, and the call will always
fail.

For the ARM SiP service:

- Add SMC function IDs for both AArch32 and AArch64;
- Increment the SiP service minor version to 2;
- Adjust the number of supported SiP service calls.

Add documentation for ARM SiP service.
